Different from ordinary digital input terminal, virtual X can be set in two ways, and can be selected through
A1-05.
When X state is determined by the state of corresponding virtual Y, whether X is valid depends on whether Y
output is valid or invalid, and X is uniquely bound to Yx (X is 1 ~ 5).
When virtual X terminal status is set by function code, the status of virtual input terminal is determined by
binary bit of function code A1-06. The following is an example of how to use the virtual X terminal.
Example 1: when virtual Y state is selected to determine virtual X state, to complete the following functions:
when AI1 input exceeds the upper and lower limits, the frequency converter will give an alarm and shut down.
The following setting methods can be adopted:
Set the function of virtual X as "user defined fault 1" (A1-00 = 38).
The virtual X terminal effective state mode is determined by virtual Y (A1-05 = xxx0); Set the output function
of virtual Y1 as "AI1 input exceeds the upper and lower limits" (A1-11 = 23).
When the AI1 input exceeds the upper and lower limits, the virtual Y1 output is in the ON state. At this time, the
virtual X1 input terminal state is valid. The virtual X1 of the frequency converter receives the user-defined fault
1, and the frequency converter will alarm Err48 and shut down.
Example 2: when the function code A1-06 is selected to set the virtual X1 state, the following functions are
completed: after the inverter is powered on, it will automatically enter the operation state. The following setting
method can be adopted:
Set the function of virtual X1 to "forward running" (A1-00=1);
Set the valid status mode of virtual X1 terminal as function code (A1-05=xxx1);
